To receive electric current, connect the conductor to a source of electric field (current source). Galvanic cells, thermobatteries and generators are the most popular. All of them will transform different types of energy to electric.
It is required to you
- Copper and aluminum conductors, arc-shaped magnet and tanks of different volumes.
Instruction
1. Receiving current by means of galvanic of an elementachtoba to make a galvanic cell, take a usual bucket, fill it with the earth and plentifully water it with the concentrated hydrochloric solution. Then insert a copper and iron plate at the edges of a bucket. Attach the voltmeter and make sure available tension. Having connected consistently several such elements, it is possible to receive the current sufficient for charging of the mobile phone.
2. For creation of more difficult galvanic cell take a usual half-liter can and fill on its bottom of copper vitriol. Then lower the copper wire curtailed into a spiral with the insulated end which is removed from banks. Fill in this design with water and cover with a zinc plate which will be in the top part banks. Attach the voltmeter to copper (positive) and zinc (negative) to electrodes – it will show tension. Connect them the conductor, and in it electric current will begin to flow.
3. Receiving current in the thermogenerator Take two conductors from a constantan (alloy of nickel and copper) and iron and solder them since two ends. Then cut one, for example, iron, and install the sensitive ampermeter in the turned-out chain. After that heat one of the soldered ends. The ampermeter will show existence of current in a chain – the thermogenerator turned out. Having made several such contours, and having connected them to the ampermeter, it is possible to achieve significant increase in current. If there is no constantan, replace it with copper, but the effect of such thermogenerator will be worse.
4. Receiving current by means of magnetic to a polyamezhd arrange poles of a powerful permanent arc-shaped magnet a frame from the copper conductor which can be rotated on two soft conductors connected to the milliamperemeter. Rotate a frame a hand, and in the conductor there will be electric current that will be reflected in indications of the milliamperemeter. In order that the soft conductor was not twisted, solder two copper rings to the ends of a frame, and on conductors establish brushes. In this case the frame can be rotated as much as long. For increase in value of the received current, use more rounds of a wire in a frame – current will increase in proportion to their quantity.
